This invention relates to a rear sight for firearms and more particularly for rifles.

One of the objects is to provide a transparent, sight which will be disposed in close proximity to the eye of the user, through which the target, together with other objects and surrounding space, may be seen.

The invention includes a movable sight disposed rearwardly of the gun-barrel upon the inclined hand-gripping part of the gun-stock so that it will be near the trigger for quick adjustments at the time of firing.

I! The invention includes a gun-sight arranged for long-range shooting as well as short, and therefore it may have inclined slidable move- ;ments longitudinally of the stock to higher or 2" lower altitudes relative to the barrel, as may be required, and corresponding to the distance to a remote target. 2b It is .an object to provide an inclined slidable rear sight of such construction and arrangement of parts that it may be moved by the thumb of the user while a finger controls the trigger, this being of great advantage in instances when the target is moving swiftly to remote distances from the marksman and repeated firing is desired, the arrangement of said inclinedly movable sight also being provided with a graduated or indexed base for specific distances upon which the sight may slide for its adjustments.

With the foregoing objects in view and others to be mentioned herein, the invention consists of the new and useful construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accom panying drawing, it being understood that changes may be made in form, size and proportions as found to be of advantage, said changes being within the scope of the invention as claimed.

In the drawing, Fig. 1 is a side view of a rifle with the gun-sighting device mounted thereon.

described in connection with the barrel 1 and stock 8 of a rifle, the barrel having a front sight 9, and the stock, as usual, having an inclined hand-gripping portion 1 ii at its junction with the end of the barrel.

The improvement to be described relates simply to the rear sight together with its construction and advantages in operation.

Numeral ll indicates an elongated base-plate which is disposed at an acute angle to the barrel and is seated upon the upper portion of the inclined hand-gripping portion In of the stock.

This base-plate ll may have any desired proportions, and it may have any suitable form in cross-section adapted to discharge its required functions.

For instance, since it provides an inclined slideway for the rear sight it should be disposed with its longitudinal axis in the vertical plane of the longitudinal axis of the gun-barrel, and

for the purpose of maintaining this base-plate in a stationary position I have shown keepers l2 in its front end which secures it to the breech of the gun-barrel. However, other keepers may be used if desired for this purpose.

As best shown in Fig. 4 of the drawing the base-plate i is approximately of T-shapein crosssection. I provide a spring-controlled carrierframe adapted to have slidable movements on the base-plate ll, said carrier-frame consisting simply of a fiat strip or body-portion l3, best shown in Fig. 3, adapted to lie upon the baseplate I I, said body-portion I3 being provided with angular holder-prongs l4 arranged in pairs and adapted to slidably engage the edges of the baseplate II and having terminal portions [5 (Fig. 4) for engaging the lower sides of the ridges of the T-shaped base-plate H.

As thus described the carrier-frame may have sliding movements upon and longitudinally of the base-plate and will be maintained thereon since the terminal parts l5 of said prongs l4 slidingly engage the ridges as mentioned.

It will be noted that the lower end of the slidable carrier-frame is provided with a thumb piece It, and therefore the user of the gun may, with a single hand, cause slidable movements of said carrier-frame between times of pressing the trigger, when repeatedly firing at moving game located at varying distances from the rifleman.

The carrier-frame is also provided with a socket-member consisting of a pair of upwardly projecting side-plates I! for receiving the spindle l8 of the lens-frame IS, a pivot 20 which traverses the side-plates and spindle operating to permit the spindle and lens-frame to have swinging movements forwardly or rearwardly to dispose the lens-frame upon the carrier frame when not in use, and to be disposed in a vertical position when in use.

The transparent imperforate lens 2| is of discform and bears circular markings 22 centrally thereof as an aid to the marksman when aiming at a target, said element 22, while distinctly visible to the marksman, not operating as an obstruction to vision.

As shown in Fig.- 5, the upper surface of the base-plate II is provided at longitudinal intervals with notches 23, and the front end of the carrier-frame with a latch spring 24 best shown in Fig. 3, said spring being of, such form that its end may engage in a selected notch for holding the carrier-frame in stationary relation relative to said base-plate, and in operation a marksman may adjust the carrier-frame so that the projectile will accurately reach the target at specific selected distances.

The notches 23 are provided for the base-plate H or may be omitted as may be desired, said notches being of advantage when the remote object is a stationary target. In instances when the target is movable these notches may be omitted.

The use of the herein described device will be appreciated by game-hunters for the reason that adjustments may be quickly made of the sight on occasions when there are moving targets at varying distances, and several shots may be fired in succession before said moving targets are beyond range.

I claim as my invention,-

1. In a gun sighting device, a flat, metallic base-plate for a rigid mounting on the stock of the gun in a position inclined to the bore of the barrel, a metallic carrier-strip slidably mounted on the base-plate and provided between its ends with an upright sight-member, and a longitudinally curved spring secured to the front end of the carrier-strip projecting forwardly to frictionally engage said base-plate and tending to prevent sliding movements of the carrier, and a thumb-piece secured to the carrier-strip for sliding said strip on the base-plate.

2. In a gun sighting device, an elongated baseplate of T-shape in cross-section provided transversely with notches and disposed on the stock of the gun in a position inclined to the bore of the barrel, a metallic carrier-strip slidably engaging and having prongs bent downwardly for embracing the opposed sides of the base-plate, a socket on the carrier-strip, a transparent sightmember having a spindle pivotally mounted in the socket, and a spring normally in engagement with the base-plate and secured to the front end of the carrier-strip, said carrier-strip being provided at its rear end with a thumbpiece for moving said carrier to positions in which the free end of said spring engages in a selected one of said notches.

3. In a gun sighting device, a flat base-plate secured to the stock of the gun in a position inclined to the bore of the barrel and having transverse notches on its upper face, a carrier-strip slidably mounted on the base-plate, a sightbearing socket projecting above and secured to the carrier-strip, and a spring secured to the carrier-strip and normally pressing against the face of the base-plate to engage in a selected notch, that part of the carrier-strip rearwardly of the sight-bearing socket being provided with a thumb-piece for moving said carrier-strip to permit the free end of said spring to engage in a selected notch of said base-plate.

4. In a gun sighting device, an elongated baseplate secured to the stock of the gun in a position inclined to the bore of the barrel, an enlongated
